[Bug 1410839] Re: Shell Command injection in ufw_backend.py
I managed to start xterm (2x) with root rights when the firewall admin
exports the profile to a path like
/.../.../;xterm;/.../
so the profile name is not the key but the path in the "file"
variable(s) in the export function .
For a workaround the export path should not be user editable but a fixed standard path an filename.

Title:
Shell Command injection in ufw_backend.py
Status in Gufw:
New
Bug description:
Firewall Administrators can be tricked by someone to export a profile
with Gufw to an special crafted file or path name wich contains shell
code.
reason is this line in ufw_backend.py :
def export_profile(self, profile, file):
commands.getstatusoutput('cp /etc/gufw/' + profile + '.profile ' + file + ' ; chmod 777 ' + file)
The rename and delete funktions are also unsave if profile name
contains shell code, like semicolons.
